[2] The Company leases land from the Israel Lands Administration ("ILA") for its Bar-Lev manufacturing facility. The lease term started on February 6, 2005. The lease is for an initial non-cancellable term of 49 years, with a renewal option of an additional 49 years. The Company analyzed the conditions set forth in ASC 840-10 and classified the land as an operating lease (since the land is not transferred to the Company at the end of the lease nor is there any option to buy the land from the ILA at any point). All payments on account of the initial term were paid in advance (based on discounted values) at the beginning of the lease, and included in the minimum lease payments to be amortized. The prepaid expenses are amortized through the term of the lease, based on the straight-line method (including the bargain renewal option term).
